# Configure RF (G Dataflow)

Version:

Configures the frequency and power level of the RF output signal.

The PXIe-5644/5645/5646, PXI/PXIe-5650/5651/5652, PXIe-5654/5654 with PXIe-5696, PXIe-5673E, and PXIe-5840 can be in the Configuration state or Generation state when you call this node.

## session in

Instrument session obtained from .

## error in

Error conditions that occur before this node runs.

The node responds to this input according to standard error behavior.

Standard Error Behavior

Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.

error in does not contain an error error in contains an error
If no error occurred before the node runs, the node begins execution normally.

If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.

If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

Default: No error

## frequency

Frequency of the generated RF signal. This value is expressed in hertz.

For arbitrary waveform generation, this input specifies the center frequency of the signal.

## power level

Power level of the generated RF signal. This value is expressed in dBm.

This input specifies the average power of the signal when the Power Level Type property is set to Average Power, which is the default setting.

Configuring the Power Level for Varying Power

To configure the power level of a waveform with varying power, set the Power Level Type property to Peak Power.

## session out

Reference to your instrument session passed to the next node.

## error out

Error information.

The node produces this output according to standard error behavior.
